3b. took a backup from step 2 and restored it to server in step 3 using: rsync -avHK [external backup device]/zimbra.bak /opt/zimbra

4. from zcs7.1.0UBUNTU10-64bit# ./install.sh.
Install process recognizes it needs to do an upgrade. Choose not to verify database integrity (read that in the forums) but install does not complete.

Looked at /opt/zimbra.install (the dummy) and noticed /opt/zimbra/zimbramon/lib/x86_64-linux-gnu-thread/multi/auto/Cwd/Cwd.so did not exist.

Renamed /opt/zimbra/zimbramon/lib/x86_64-linux-gnu-thread/multi/auto/Cwd/Cwd.so to ..../Cwd.so.8_04 then ran zcs7.1.0UBUNTU10-64bit# install.sh. This time the install completes.

This is where I'm at now:
